lVlEASURlNG-FAUCET FOR LIQUEFIED GAS.

SPECIFICATION forming part of Letters Patent No. 643,406, dated February 13, 190; Application filed September 2.6, 1899. Serial No. 731,718. (No model.)

T0 all whom t may concer-n:

Be it known that I, WILHELM FRIEDRICH apparatus for drawing off determined quan-- tities of liquid carbonic acid or of high-pressure gases or vapors from a source of supply into vessels, such as bottles, with reduction of pressure. For this purpose a chamber of lixed capacity is closed in by two valves, which valves by means of a mechanism common to both can be adjusted simultaneously in opposite directions. This chamber in one position of the valves is open toward the source of supply and closed toward the vessel destined or intended to receive the carbonio-acid or other gas or vapor, and in the other position of the valves the chamber is closed toward the source of supply and open toward the said vessel. The change in the position of Athe valves, however, takes place suddenly and so that the one valve isalways closed be fore the other is opened.

The apparatus .may be suitably utilized in the preparation of carbonio beverages-wiz., beverages containing carbonio acid.

The accompanying drawing illustrates in vertical section the object of the invention.

The part c of the casing a is to be placed in connection with the source of supply, (carbonio-acid bottle.) andthe vessel b-for instance, a bottle partially filled with water-is to be joined gas-tight to the portion a2 of the casing. In the casing u. two valves c c', having gas-tight washers, are arranged coaxially under spring-pressure. The chamber d, situated between these two valves c c', possesses a capacity proportionate to the quantity it is desired to draw off. The simultaneous action of the valves is obtained by means of the gearing e e and the eccentric f j, the position of the latter being such that when one-for in-v stance, the lower one-holds open the valve o', belonging to it, the othermfor instance, the upper one-closes its valve,and vice versa. The closing force of the spring is aided by the pressure of the gas, liquid, or vapor. In

the position illustrated of the eccentrics f f and valves c c it is supposed that the connection between the chamber d and the source of supply has been closed and that between chamber d andthe vessel b opened. The con# tents of the chamber discharge into the ves-V sel b through the narrow aperture d3, which reduces the pressure to the desired amount. After drawing off the contents of the charnber d the valves c c are turned by the gear# ing e e and the eccentrics ff actuated by closing of each valve always takes place at the beginning and the opening thereof at the end of half a revolution of the eccentrics ff', the one valveis already sh'ut when the other Opens, consequently preventing a free cur rent of carbonio acid or the like from passing through the chamber.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. An apparatus for drawing on? determined quantities of liquid carbonio acid, compressed gases, and vapors, comprising a casing having an inlet and an outlet, an inlet-valve opening outwardly, an outlet-valve opening inwardly, springs tending to close the respective valves, a chamber of fixed capacity in the casing between said valves, two rotatably; mounted eccentrics for opening the respective valves, said eccentrics being so set as to open the valves alternately and to permit one to close before the other is opened, means for operating both eccentrics simultaneously and means at the outlet for diminishing the pressure lof the liquid gas or vapor delivered.

2,. An apparatus for drawing off determined quantities of liquid carbonio acid, com pressed gases, and vapors, comprising a casing havin g an inlet and an outlet, an inlet-valve opening outwardly, an outlet-valve opening inwardly, springs tending to close the respective valves, a chamber of fixed capacity in the casing between said valves, two rotatablymounted eccentries for opening the respective valves, said eccentrics being so set as to open the valves alternately and to permit one to close before the other is opened, means for operating both eocentrics simultaneously and a contracted passage as at the outlet to diminish the pressure of the fluid delivered.

3. Anapparatusfordrawingoffdetermined quantities of fluids, coxnprisinga casing @having an inlet, a contracted outlet a3, means for connecting said casing hermetieally to the source of supply at the inlet and to the receiver at the outlet, and a chamber d, of fixed zo capacity, an inlet-valve o between the inlet and the chamber cl and opening outwardly, an outlet-valve o', between the outlet and the chamber d and opening inwardly, springs tending to close the respective valves, two rotatively-mounted eccentrics f and f, for operating the respective valves c and c', and manually-operative gearing connecting said eccentrics and adapted to rotate the same simultaneously.

In witness whereof I have hereunto signed my name, this 14th day of September, 1899, in the presence of two subscribing witnesses.

. WILHELM FRIEDRICH FRITZ.
